2.4. Application of Reynolds Transport Theorem

Try these first

1. 1.

   What is an extensive property? Give an example.

   Hint

   Think about properties that change with how much material is present.

2. 2.

   What is an intensive property? Give an example.

   Hint

   Consider properties that remain the same regardless of the amount.

3. 3.

   What is an extensive property?

   • A property dependent on the size of the system
   • A property independent of the size of the system
   • Both A and B

   Hint

   Think of properties related to the quantity of material.

4. 4.

   True or False: The Reynolds Transport Theorem applies only to extensive properties.

   • True
   • False

   Hint

   Consider if the theorem deals with other types of properties in fluid mechanics.

5. 5.

   A fluid system experiences an inflow of 5 kg/s and an outflow of 3 kg/s. If the initial mass in the system is 20 kg, calculate the mass in the system after 10 seconds using the Reynolds Transport Theorem.

   Hint

   Use the mass flow rate equation to find the change over time.

6. 6.

   Assess how the Reynolds Transport Theorem could be applied to model the flow of a contaminant in a river with multiple inputs and outputs.

   Hint

   Think of all inflows and outflows impacting the contaminant concentration.
